I have two table named Soft and Web, table containing multiple data in that which data is different that data I want. For Ex :
In soft table containing 5 data i.e.
Also in Web table containing 5 data i.e.
Now I want output i.e.
I have done query but unfortunately didnt succed, lets see my query i.e.
SELECT DISTINCT soft.GSTNo AS SoftGST
,web.GSTNo AS WebGST
,soft.InvoiceNumber AS SoftInvoice
,web.InvoiceNumber AS WebInvoice
,soft.Rate AS SoftRate
,web.Rate AS WebRate
FROM soft
LEFT OUTER JOIN web ON web.GstNo = soft.GSTNo
AND web.InvoiceNumber = soft.invoicenumber
AND web.rate = soft.rate
Also I apply inner join bt same thing didnt work.
You can achieve this by
;WITH cte_soft AS
(SELECT * FROM soft
EXCEPT
SELECT * FROM web)
,cte_web AS
(SELECT * FROM web
EXCEPT
SELECT * FROM soft)
SELECT *
FROM
(SELECT gst softgst, NULL webgst, invoice softinvoice, NULL webinvoice, rate softrate, NULL webrate
FROM cte_soft
UNION ALL
SELECT NULL, gst, NULL, invoice, NULL , rate
FROM cte_web) tbl
ORDER BY coalesce(softgst, webgst),coalesce(softinvoice,webinvoice)
Fiddle
You can use full join:
SELECT s.gst as softgst, w.gst as webgst,
s.invoice as softinvoice, w.invoice as webinvoice,
s.rate as softrate, w.rate as webrate
FROM soft s FULL JOIN
web w
ON s.gst = w.gst AND s.invoice = w.invoice AND s.rate = w.rate
WHERE s.gst IS NULL OR w.gst IS NULL
ORDER BY COALESCE(s.gst, w.gst), COALESCE(s.invoice, w.invoice);
No subqueries are CTEs are needed. This is really just a slight variant of your query.

I have two tables that has the same columns numbers and names
and I want to join its columns.
I have this table called inicial_dolares
And have this other table called inicial_cordobas
I am looking for this result
I've tried do this with joins but does not work.
the common column is id_arqueo is a integer.
and I tried this SQL union but vertically
but does not work.
SELECT IC.id_arqueo,
IC.id_detalle,
IC.descripcion,
IC.denominacion,
IC.cantidad,
IC.total,
ID.id_arqueo,
ID.id_detalle,
ID.descripcion,
ID.denominacion,
ID.cantidad,
ID.total
FROM dbo.inicial_cordobas IC
LEFT JOIN dbo.inicial_dolares ID
ON ID.id_arqueo = IC.id_arqueo
--this query returns to me 168 rows because the join looks for coincidence and
--one table has 14 and the other has 12 rows.
you need row_number() to join your 2nd table.
SELECT IC.id_arqueo,
IC.id_detalle,
IC.descripcion,
IC.denominacion,
IC.cantidad,
IC.total,
ID.id_arqueo,
ID.id_detalle,
ID.descripcion,
ID.denominacion,
ID.cantidad,
ID.total
FROM
(select row_number() over (order by id_detalle) rn, * from dbo.inicial_cordobas) IC
LEFT JOIN
(select row_number() over (order by id_detalle) rn , * from dbo.inicial_dolares) ID
ON ID.id_arqueo = IC.id_arqueo and IC.rn = ID.rn
The id_detalle columns also have a relationship that can be expressed mathematically and used:
SELECT IC.id_arqueo,
IC.id_detalle,
IC.descripcion,
IC.denominacion,
IC.cantidad,
IC.total,
ID.id_arqueo,
ID.id_detalle,
ID.descripcion,
ID.denominacion,
ID.cantidad,
ID.total
FROM dbo.inicial_cordobas IC
LEFT JOIN dbo.inicial_dolares ID
ON ID.id_arqueo = IC.id_arqueo
AND ic.id_detalle + 14 = id.id_detalle
The id_detalle in ic is always 14 less than the id_detalle in id so we can make a joint condition where we add 14 to the value in ic and then relate it to the value in id
This is possibly an important learning point that joins don't have to always take the form tableA.columnA = tableB.columnB. Anything that can be expressed as a truth may work as a join condition, including formulas and maths operations on either side of the =
Adding back some original info for historical purposes as I thought simplifying would help but it didn't. We have this stored procedure, in this part it is selecting records from table A (calldetail_reporting_agents) and doing a left join on table B (Intx_Participant). Apparently there are duplicate rows in table B being pulled that we DON'T want. Is there any easy way to change this up to only pick the first match on table B? Or will I need to rewrite the whole thing?

WHERE DialedNumber IN ( SELECT DialedNumber

AND ConnectedDate BETWEEN #LocStartDate AND #LocEndDate
AND (#LocQueue IS NULL OR AssignedWorkGroup = #LocQueue)
Simpler version: how to change below to select only first matching row from table B:
SELECT columnA, columnB FROM TableA LEFT JOIN TableB ON someColumn
I changed to this per the first answer and all data seems to look exactly as expected now. Thank you to everyone for the quick and attentive help.

AND calldetail_reporting_agents.RemoteNumber = ip.ConnValue
AND ip.HowEnded = '9'
AND ip.Recorded = '0'
AND ip.Duration > 0
AND ip.Role = '1') Intx_Participant
WHERE DialedNumber IN ( SELECT DialedNumber

You can try to OUTER APPLY a subquery getting only one matching row.
...
FROM calldetail_reporting_agents
OUTER APPLY (SELECT TOP 1
*
FROM intx_Participant ip
WHERE ip.callidkey = calldetail_reporting_agents.callid) intx_participant
WHERE ...
You should add an ORDER BY in the subquery. Otherwise it isn't deterministic which row is taken as the first. Or maybe that's not an issue.
How to achieve 'Only in' condition in oracle?
I have two tables 'PlanPlanSet' and 'ExcludedPlans'. PlanPlanSet contains Plans and the Plan set associated to each plan. I want to fetch all records from PlanPlanSet where having Plan ONLY IN ExcludedPlans.
PlanPlanSet table
Plan1 - Planset1
Plan2 - Planset2
Plan3 - Planset3
Plan4 - Planset1
Plan5 - Planset5
ExcludedPlans Table
Plan1
Plan2
Here Planset1 contains Plan1 and Plan4, and Planset2 contains only Plan2. So Planset1 should not be excluded and Planset2 should be excluded.
Something like,
select pps.planset
from PlanPlanSet pps
where pps.planNumber only in (select ex.planNumber
from ExcludedPlan ex);
You want everything from PLANSETS where every plan within that planset is in the list of excluded plans.
Thinking about this relationally you need to join the two tables together and discover where the number of plans on each side is the same. This means we must allow for them to be different implying a LEFT OUTER JOIN.
select p.planset
from plansets p
left outer join excludedplans e
on p.plan = e.plan
group by p.planset
having count(p.plan) = count(e.plan)
This assume that PLANSETS is unique on PLANSET and PLAN and that EXCLUDEDPLANS is unique on PLAN. If this assumption is incorrect then you'll need to count(distinct ...
If you want all data from PLANSETS then the logic can be put into an analytic function
select *
from ( select p.*
, count(p.plan) over (partition by p.planset) as planset_ct
, count(e.plan) over (partition by p.planset) as excluded_ct
from plansets p
left outer join excludedplans e
on p.plan = e.plan
)
where planset_ct = excluded_ct
This is supposed to find only such plansets of which all the plans are present in ExcludedPlans table. In case all the rows for such plansets are desired omit the distinct on the first row and add any columns needed.
Select distinct planset
From PlanPlanSet ps1
Where
exists
(
Select selected.planset
From
(
Select ps2.planset, count(*) ct, sum(decode(ep2.plan, null, 0, 1)) present
From PlanPlanSet ps2
Left join ExcludedPlans ep2 on ep2.plan = ps2.plan
Group by ps2.planset
) selected
Where selected.ct = selected.present and ps1.planset = selected.planset
)
If on the contrary only such plansets of which not all the plans are present in ExcludedPlans table should be selected, then change the subquery WHERE condition to selected.all <> selected.present
This query returns all the records in PlanPlanSet which are sets of excluded plans only:
select * from PlanPlanSet pss
where not exists
( select planname from planPlanSet x
where x.setname = pss.setname
minus
select planname from ExcludedPlans)
/
The MINUS operator produces a set of records from the top subquery which don't exist in the bottom subquery. When the result is an empty set the plan set contains only excluded plans. MINUS is not a very fast operation, so this may not be the best approach if you have a large number of records to process. However, it does have the advantage of retrieving columns of PlanPlanSet, not just the setname.
LiveSQL demo.
I have a simple SQL table containing some values, for example:
id | value (table 'values')
----------
0 | 4
1 | 7
2 | 9
I want to iterate over these values, and use them in a query like so:
SELECT value[0], x1
FROM (some subquery where value[0] is used)
UNION
SELECT value[1], x2
FROM (some subquery where value[1] is used)
...
etc
In order to get a result set like this:
4 | x1
7 | x2
9 | x3
It has to be in SQL as it will actually represent a database view. Of course the real query is a lot more complicated, but I tried to simplify the question while keeping the essence as much as possible.
I think I have to select from values and join the subquery, but as the value should be used in the subquery I'm lost on how to accomplish this.
Edit: I oversimplified my question; in reality I want to have 2 rows from the subquery and not only one.
Edit 2: As suggested I'm posting the real query. I simplified it a bit to make it clearer, but it's a working query and the problem is there. Note that I have hardcoded the value '2' in this query two times. I want to replace that with values from a different table, in the example table above I would want a result set of the combined results of this query with 4, 7 and 9 as values instead of the currently hardcoded 2.
SELECT x.fantasycoach_id, SUM(round_points)
FROM (
SELECT DISTINCT fc.id AS fantasycoach_id,
ffv.formation_id AS formation_id,
fpc.round_sequence AS round_sequence,
round_points,
fpc.fantasyplayer_id
FROM fantasyworld_FantasyCoach AS fc
LEFT JOIN fantasyworld_fantasyformation AS ff ON ff.id = (
SELECT MAX(fantasyworld_fantasyformationvalidity.formation_id)
FROM fantasyworld_fantasyformationvalidity
LEFT JOIN realworld_round AS _rr ON _rr.id = round_id
LEFT JOIN fantasyworld_fantasyformation AS _ff ON _ff.id = formation_id
WHERE is_valid = TRUE
AND _ff.coach_id = fc.id
AND _rr.sequence <= 2 /* HARDCODED USE OF VALUE */
)
LEFT JOIN fantasyworld_FantasyFormationPlayer AS ffp
ON ffp.formation_id = ff.id
LEFT JOIN dbcache_fantasyplayercache AS fpc
ON ffp.player_id = fpc.fantasyplayer_id
AND fpc.round_sequence = 2 /* HARDCODED USE OF VALUE */
LEFT JOIN fantasyworld_fantasyformationvalidity AS ffv
ON ffv.formation_id = ff.id
) x
GROUP BY fantasycoach_id
Edit 3: I'm using PostgreSQL.
SQL works with tables as a whole, which basically involves set operations. There is no explicit iteration, and generally no need for any. In particular, the most straightforward implementation of what you described would be this:
SELECT value, (some subquery where value is used) AS x
FROM values
Do note, however, that a correlated subquery such as that is very hard on query performance. Depending on the details of what you're trying to do, it may well be possible to structure it around a simple join, an uncorrelated subquery, or a similar, better-performing alternative.
Update:
In view of the update to the question indicating that the subquery is expected to yield multiple rows for each value in table values, contrary to the example results, it seems a better approach would be to just rewrite the subquery as the main query. If it does not already do so (and maybe even if it does) then it would join table values as another base table.
Update 2:
Given the real query now presented, this is how the values from table values could be incorporated into it:
SELECT x.fantasycoach_id, SUM(round_points) FROM
(
SELECT DISTINCT
fc.id AS fantasycoach_id,
ffv.formation_id AS formation_id,
fpc.round_sequence AS round_sequence,
round_points,
fpc.fantasyplayer_id
FROM fantasyworld_FantasyCoach AS fc
-- one row for each combination of coach and value:
CROSS JOIN values
LEFT JOIN fantasyworld_fantasyformation AS ff
ON ff.id = (
SELECT MAX(fantasyworld_fantasyformationvalidity.formation_id)
FROM fantasyworld_fantasyformationvalidity
LEFT JOIN realworld_round AS _rr
ON _rr.id = round_id
LEFT JOIN fantasyworld_fantasyformation AS _ff
ON _ff.id = formation_id
WHERE is_valid = TRUE
AND _ff.coach_id = fc.id
-- use the value obtained from values:
AND _rr.sequence <= values.value
)
LEFT JOIN fantasyworld_FantasyFormationPlayer AS ffp
ON ffp.formation_id = ff.id
LEFT JOIN dbcache_fantasyplayercache AS fpc
ON ffp.player_id = fpc.fantasyplayer_id
-- use the value obtained from values again:
AND fpc.round_sequence = values.value
LEFT JOIN fantasyworld_fantasyformationvalidity AS ffv
ON ffv.formation_id = ff.id
) x
GROUP BY fantasycoach_id
Note in particular the CROSS JOIN which forms the cross product of two tables; this is the same thing as an INNER JOIN without any join predicate, and it can be written that way if desired.
The overall query could be at least a bit simplified, but I do not do so because it is a working example rather than an actual production query, so it is unclear what other changes would translate to the actual application.
In the example I create two tables. See how outer table have an alias you use in the inner select?
SQL Fiddle Demo
SELECT T.[value], (SELECT [property] FROM Table2 P WHERE P.[value] = T.[value])
FROM Table1 T
This is a better way for performance
SELECT T.[value], P.[property]
FROM Table1 T
INNER JOIN Table2 p
on P.[value] = T.[value];
Table 2 can be a QUERY instead of a real table
Third Option
Using a cte to calculate your values and then join back to the main table. This way you have the subquery logic separated from your final query.
WITH cte AS (
SELECT
T.[value],
T.[value] * T.[value] as property
FROM Table1 T
)
SELECT T.[value], C.[property]
FROM Table1 T
INNER JOIN cte C
on T.[value] = C.[value];
It might be helpful to extract the computation to a function that is called in the SELECT clause and is executed for each row of the result set
Here's the documentation for CREATE FUNCTION for SQL Server. It's probably similar to whatever database system you're using, and if not you can easily Google for it.
Here's an example of creating a function and using it in a query:
CREATE FUNCTION DoComputation(#parameter1 int)
RETURNS int
AS
BEGIN
-- Do some calculations here and return the function result.
-- This example returns the value of #parameter1 squared.
-- You can add additional parameters to the function definition if needed
DECLARE #Result int
SET #Result = #parameter1 * #parameter1
RETURN #Result
END
Here is an example of using the example function above in a query.
SELECT v.value, DoComputation(v.value) as ComputedValue
FROM [Values] v
ORDER BY value
I have a SQL Server 2005 query that I'm trying to assemble right now but I am having some difficulties.
I have a group by clause based on 5 columns: Project, Area, Name, User, Engineer.
Engineer is coming from another table and is a one to many relationship
WITH TempCTE
AS (
SELECT htce.HardwareProjectID AS ProjectId
,area.AreaId AS Area
,hs.NAME AS 'Status'
,COUNT(*) AS Amount
,MAX(htce.DateEdited) AS DateModified
,UserEditing AS LastModifiedName
,Engineer
,ROW_NUMBER() OVER (
PARTITION BY htce.HardwareProjectID
,area.AreaId
,hs.NAME
,htce.UserEditing ORDER BY htce.HardwareProjectID
,Engineer DESC
) AS row
FROM HardwareTestCase_Execution AS htce
INNER JOIN HardwareTestCase AS htc ON htce.HardwareTestCaseID = htc.HardwareTestCaseID
INNER JOIN HardwareTestGroup AS htg ON htc.HardwareTestGroupID = htg.HardwareTestGroupId
INNER JOIN Block AS b ON b.BlockId = htg.BlockId
INNER JOIN Area ON b.AreaId = Area.AreaId
INNER JOIN HardwareStatus AS hs ON htce.HardwareStatusID = hs.HardwareStatusId
INNER JOIN j_Project_Testcase AS jptc ON htce.HardwareProjectID = jptc.HardwareProjectId AND htce.HardwareTestCaseID = jptc.TestcaseId
WHERE (htce.DateEdited > #LastDateModified)
GROUP BY htce.HardwareProjectID
,area.AreaId
,hs.NAME
,htce.UserEditing
,jptc.Engineer
)
The gist of what I want is to be able to deal with empty Engineer columns. I don't want this column to have a blank second entry (where row=2).
What I want to do:
Group the items with "row" value of 1 & 2 together.
Select the Engineer that isn't empty.
Do not deselect engineers where there is not a matching row=2.
I've tried a series of joins to try and make things work. No luck so far.
Use j_Project_Testcase PIVOT( MAX(Engineer) for Row in ( [1], [2] ) then select ISNULL( [1],[2]) to select the Engineer value
I can give you a more robust example if you set up a SQL fiddle
